Abstract

This invention is an apparatus and method for vaporizing any one of hard tissue and deposits (36) on hard tissue (52). A scanner (22) substantially continuously scans a target area and directs a pulsed laser (20) beam during the scanning so as to vaporize portions of the target area to form a vaporized target area of a desired size and shape. Non-limiting examples of applications include those for performing a stapedectomy, drilling in teeth, vaporizing of plaque, and caries.
